在已经成形的工件上再冲多个孔,以前往往需要在不同的冲床上进行多次操作.设计专用冲孔机生产线,可以一次装卡,同时完成3个纵向孔、4个横向孔的加工.该机稍作调整,还可以用来同时加工多个纵向孔、多个横向孔.%To punch again more than one hole on the formed workpiece, multiple operations in different punching machine tools are often required before. A dedicated production line of punching machine was designed, by which three vertical holes and four horizontal holes were processed simultaneously with once clamping. After making some minor adjustments, the machine can also be used to process a number of vertical holes and a number of horizontal holes.
